Muscle Injuries — Group XV (Mesial Thigh Muscles) — Diagnostic Code 5315

Understanding a Group XV Muscle Injury Rating

Group XV covers the mesial thigh muscle group, located on the inner side of the thigh. These muscles are responsible for key movements of the lower body, including:

  • Adduction of the hip (drawing the thigh inward toward the body)
  • Flexion of the hip (bending at the hip)
  • Flexion of the knee (bending at the knee)

The specific muscles that make up this group are:

  1. Adductor longus
  2. Adductor brevis
  3. Adductor magnus
  4. Gracilis

Injuries to these muscles can affect a person's ability to move the hip and knee. The VA rates this condition under § 4.73, within the Muscle Injuries body system.

Available Rating Levels

The VA assigns a disability rating based on how severe the muscle injury is. Under Diagnostic Code 5315, the available levels are:

RatingLevel of Disability
30%Severe
20%Moderately Severe
10%Moderate
0%Slight

What the VA Looks For

When rating a Group XV muscle injury, the VA evaluates the severity of the muscle disability, categorizing it as slight, moderate, moderately severe, or severe. The rating level reflects how significantly the injury affects the function of the mesial thigh muscles — including the hip and knee movements these muscles control.

This information is provided for general educational purposes and is drawn directly from the VA rating schedule under 38 CFR § 4.73, Diagnostic Code 5315. Individual ratings depend on the specific facts and medical evidence in each case.

These criteria are a rendering of § 4.73, diagnostic code 5315. The official version is the one that governs your rating.

How to claim this

Knowing the criteria is the first half. Getting your file to show them is the second.

  1. Find your level in the stack

    Read each rung against what your medical records already say. The level your records document today is the one the VA can support today.

  2. Name the gap

    Look at the rung above yours and write down exactly what it asks for that your file does not show yet — a diagnosis, a measurement, a prescribed brace, a doctor’s opinion linking it to service.

  3. Claim it by code

    File under diagnostic code 5315 and attach the evidence for the level you are asking for. Other Muscle Injuries codes may cover your secondary conditions.
